Abstract: A B S T R A C T        An improved trigger mechanism for a rotating frame animal trap includes a single plate which is bent along its transversely extending center line and includes end portions which are contoured to rotatably engage one of the side portions of a trap frame.   Spaced holes defined through the plate along the center line receive respective prongs of a two-prong bent wire trigger arm which is supported by the folded plate. A tab is cut in the plate and bent out of plane to serve as a wedge for securing the bent wire trigger arm along the center line.  Cut-out portions from opposite ends of the plate in the region of the contoured portions provide exposure of the surrounded frame portion side to permit a latching mechansim, which is pivotally secured to another frame, to releasably engage the exposed portion of the frame on which the trigger mechanism is supported.  The trigger mechanism is constructed for release when the trigger arm is engaged by an animal from any direction.

Abstract: Isothermal Positive Displacement Machinery Abstract Positive displacement isothermal gas cycle machinery is designed with explicit control of the heat flow between the gas, the walls of the chamber and a thermal reservoir externally of the chamber. The control is achieved by providing a large chamber wall area to chamber volume ratio through the use of bellows-like walls having a configuration that ensures during each stroke numerous heat exchanges between the working gas and the bellows-like walls.  The machinery includes Stirling cycle heat pumps and motors and isothermal compressors.  Significant gains in thermal efficiency, up to a factor of 2, are attain-able because the largest inefficiency in all isothermal machinery is imperfect control of heat flow.  A regenerator for the isothermal machinery minimizes cycle losses due to gas transfer friction, gas thermal conduction, dead volume, regenerator heat mass, regenerator heat mass thermal skin depth, and regenera-tor mass thermal conductivity in the gas flow direction.

Abstract: FABRICATION OF SEMICONDUCTOR MODULES WITH CERAMIC SUBSTRATES AND DETECTION OF RESIDUAL GLASS                 Abstract of the Disclosure To detect residual  glass,  such as appears at semiconductor chip pads and via holes during the fabrication of alumina/glass ceramic substrates that are used as supports for the semiconductor devices, the glass used for forming the ceramic substrates is doped with a rare earth oxide.  During the manufacturing process, the ceramic structures are irradiated after firing with radiation of wavelengths in the range 350-500 nanometers to induce the glass to fluoresce, thereby revealing the residual glass on the surface of the metallic interconnector pads.  If residual glass is present,  the parts  are  reworked,  or  scrapped if necessary.

Abstract: ABSTRACT            A rack contains a number of shelves (109) arranged on top of each other, which carry, among other things, board magazines (110) with printed circuit boards (111). An apparatus for cooling the aforesaid printed circuit boards containing telecommunications or electronic equipment in each rack (102) is based on the principle that one or more shelves in the rack are integrated each with its own heat exchanger, which is equipped with cooling flanges and at least one tubular coil. The heat exchanger is connected to a cooler (117) for a coolant. The heat exchanger (12) covers the greater part of the horizontal plane of the shelf. Extensive heat-conducting contact surfaces are provided between the board magazines and the body of the shelf and between the latter and the heat exchangers. Each heat exchanger and the cooler are arranged to permit a high packing density of the aforesaid telecommunications equipment in the rack and to contribute towards removing heat emitted by the equipment by means of heat conduction via the aforesaid extensive contact surfaces. In a first embodiment, the total shelf cooling function can thereby provide for the aforesaid removal of heat unassisted. This heat removal is also provided for by natural convection at the hot and cold surfaces and by radiation. In a second embodiment, the shelf cooling func-tion is combined with a row cooling function (open or closed), air conditioner or similar installation.

Abstract: SIDE POCKET MANDREL          Abstract of the Disclosure A high-strength side pocket mandrel for high pressure service having a full-opening bore throughout its length but having a bore of keyhole shape above its receptacle bore to provide minimal but ample space for operation of a kickover tool for installing devices in the receptacle bore and provid-ing strengthened walls for withstanding greater forces which would tend to burst or collapse the mandrel.          Background of the Invention Field of the Invention This invention relates to gas lift apparatus for wells and more particularly to side pocket mandrels for use in gas lift wells.    Description of the Prior Art Side pocket mandrels have long been used in wells for many years with good results, but as gas lift techniques are practiced at greater and greater depths in wells, demands for stronger side pocket mandrels increase.    Side pocket mandrels are necessarily somewhat bulbous in structure and have appreciable lateral area subjected to internal and external pressures which tend to rupture or collapse them, and they are not well suited to resist such forces acting upon them.    Further, many mandrels are used in wells equipped with dual tubing strings and,  therefore,  are flattened to a generally oval cross-section to permit the passage of one mandrel past another in casing of reasonable size so that either such tubing string can be pulled from the well without disturbing  the other  tubing string.   Flattened or oval

Abstract: ABSTRACT OF THE DISCLOSURE         This filter module comprises a rectangularly shaped housing made from four separate parts - namely a pair of rectangularly shaped front and rear sections, respectively, and a pair of rectangular end panels or caps releasably fastened to opposite ends of the front and rear sections to hold them in registry with each other.  The two and panels have dovetail-shaped tongue and groove connections with confronting surfaces on the front and rear sections of the module, so that the end panels can be shifted in one direction to secure the front and rear sections together, and in another direction to disassemble the front and rear sections.  A plurality of gas discharge tubes project from the rear section coaxially into a plurality of filter tubes, which project rearwardly from gas inlet openings in the front section of the module.  Conventionally shaped spinner elements are fixed in the forward ends of the filter tubes to cause incoming gas to be swirled coaxially in the filter tubes, whereby dust and moisture in the swirling gases are urged radially outwardly and through annular spaces between each pair of cooperating tubes to a bleeder duct, which connects a dust bin, or the like to one end of the module.  The remaining, clean portions of the gases pass directly from the filter tubes into the registering ends of the discharge tubes for discharge out of the back of the module.

Abstract: ABSTRACT           A fluid flow machine wherein a diaphragm pump is driven by an electromagnet and is confined in a pressure-resistant capsule together with the electro-magnet as well as with the electronic control unit for the electromagnet.  The constituents of the capsule are connected to each other so that they form one or more gaps each having a configuration and dimensions such as to prevent the propagation of flames and/or sparks from the interior of the capsule to the surrounding area.  This renders it possible to use the machine in an explosive atmosphere, even if the pump is designed to deliver metered quantities of flammable fluids.  A second gap of the above outlined character is provided between two portions of the capsule where a reciprocable plunger extends toward the diaphragm. Additional gaps are provided in a removable cover of the capsule at each of several locations where rotary and/or reciprocable adjusting devices extend from the interior of the capsule so that they can be manipulated in order to change the extent of movement of the armature of the electromagnet, to adjust one or more potentiometers or to actuate one or more switches. Further safety gaps can be provided in regions where the terminal or terminals of one or more electric cables extend into the capsule and/or where a light-transmitting cylinder is installed in the capsule to allow for observation of a signal generating device which is installed in the interior of the capsule.
